Letters Patent N 102,260, dated April 26, 1870.

IMPROVEMENT IN CONVERTING RECIPROCATING- INTO ROTARY MOTION.

The Schedule referred to in these Letters Patent and making part of the same.

I, JoAoHIM F. 'HABTMANN, of the city of Richmond, county of Wayne and State of Indiana, have invented certain Improvements in Machinery for (Jonverting Reciprocating into Rotary Motion, of which the following is a specification:

Nature and objects of the Invention.

My invention relates to combining with two circular racks, which are stationary, certain cog-wheels,

pinious, ratchets, and pawls, hereafter more fully explained, for the purpose of converting reciprocating General Description. The ,sameletters refer to corresponding parts in the fsever al figures.

A is a segment of a circular rack.

B is a segment of a circle, toothed.

G is aframc, in which the journals of the shaft I turn, and'in which -the shaft H is secured, and on which the cog-wheels and pinious revolve (except the pinion E.) l

D is a large cog-wheel, with the edge projecting on each side, on the inside of which there are ratchetteeth on both sides, indicated by the letters S S, which may be made square if desired.

E is a cogged pinion.

F is a cog-wheel,-gearing into the rack A.

G is a pinion, gearing into the segment B.

H is a shaft,

I is an arboror shaft.

'K is an apertureor socket cut in the flange Q to receive the pawl L, and in which the said pawl L operates, actuated by the spring P. L is a pawl. M is a pin.

ets S S in the wheel D, while the pawl L, on the opof the lever B.

- Operation.

-It will be seen that by moving the lever B in the direction indicated by the arrow 1, the top of the wheel D will revolve in the same direction, and, by moving the lever toward the arrow 2, the top of the wheel D will revolve toward arrow 1 also.

The said wheel D being actuated in the first instance (as above), by the cogs ofpinion G rolling in the cogs of segment B, one of the pawls L catching in the ratchposite side of the wheel D, runs loose, and in the second instance (as above) the piuionl is actuated by cogs in the circle A, while the'wheel D is turned by the pawl L in the directionfirst mentioned, 50- that the pinion'E is turned in one direction while the lever is forced either-way.

- Construction.

The wheels and segments are-made 0t castiron. The shafts orarbors are made of wrought iron, and the sizes of wheels and pinious proportioned so as to give the pinion E the same velocity at each vibration I am aware that there are contrivanccs-for converting reciprocating into rotary. motion. I therefore do not claim converting reciprocating into rotary motion.

Claim.

I claim combining and arranging the wheel D, segment A, pinion F, pinion G, segment B, pinion E, ratchets S, pawl L, and spring I, in connection with frame 0 and shafts H and-I, arranged and operated as above set forth.
